NITED STATES PATENT FRANK JEWETT, OF HARTFORD, CONNECTICUT, ASSIGNOR TO OWEN H. JONES, OF SAME PLACE.

BALL-COCK.

SPECIFICATION forming part of Letters Patent No. 663,231, dated December 4, 1900.

Application filed September 18, 1899. Serial No. 730,864. (No model.)

To all whom it may concern.-

Be it known that I, FRANK J EWETT, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented new and useful.Im-

provements in Ball-Cocks, of which the following is a specification.

of valve easily accessible for repairs and op erative under varying pressures and by means of the ordinary float and lever commonly used with ball-cocks of this general class.

Referring to the drawings, Figure 1 is a top view of the ball-cock, showing the valve-body cut away in horizontal section. Fig. 2 is a view in central vertical section through the structure. Fig. 3 is a plan view of the removable valve-seat and in cross-section through the valve-body.

In the accompanying drawings the letter a denotes a valve-body having a chamber 12, a water-inlet c, and an outlet (1, the latter being arranged (in the form of the present embodiment of the invention) at the side of the chamber 1) which is in line with the inlet-' opening a. The chamber 5 is larger in diameter than the inlet 0, and a cap e is secured, as by means of screws f, to the valvebody at one end. The cap 6 has a flange or shoulder e, that enables a close joint to be formed between the parts. A tubular projection g on the inner side of the cap is of a suitable length to bring its edge into close contact with the removable valve-seat h,

which is closely fitted in a socket a in the bottom of the chamber 1), a packing-ring i, of suitable material, being borne on the rear of the seat It and forming a somewhat-elastic bearingsurface for the end of the projection g. This removable seat h may be made of the same form on its opposite faces, so as to be reversible on the seat. The flange g, that projects from the part 9 within the chamber and extends to the inner surface of the Wall, forms a guide that aids to properly center the valve 10, the shank lo of which extends through the cap e, and it also forms a shield to prevent the water from flowing against the under surface of the cap with a velocity or under a pressure which would cause the unpacked joint at the edge of the cap to leak.

The valve 70 reciprocates within the chamber or space in the enlarged inner end of the projection g, and the ports 9 g formed through the wall of this part, provide for the free flow of water to the outlet (1 when the valve 75 is lifted from its seat.

On the outer surface of the cap 6 a bracket 1 supports a lever on by means of a pivot-pin passing through the parts, and a roller n on a pin 'n on the valve-spindle k is located in the slot m in the lever m, so that as the lever is rocked on its pivot the valve-spindle is reciprocated. A float-lever 0 is secured to the other arm of the lever and is moved by means of the usual float, that is controlled as to its position by the water-level within the tank to which the ball-cock is attached, it being of course understood that the valve-body a is provided with suitable means of attachment to a tank and to a supply-pipe.

The operation of the device will be readily understood from the foregoing description of the several parts and their related positions in the combination.

What I claim as my invention, and desire to secure by Letters Patent, is

In a ball-cock in combination, a valve-body having a chamber, a water-inlet at one end of the chamber, an opening at the opposite end and an outlet at the side of the chamber, a cap adapted to close the opening in the chamber and having a tubular projection extending inward toward the inlet side of the chamber with its inner end resting against the valve-seat, a flange on this projection ex-
